This module uses the LT4320 chip to control four high-power MOS transistors NCEP023N10LL (100V 300A 2. Ω) to conduct in a time-sharing manner, thereby converting AC power to DC power. This module uses industrial grade double-sided 2OZ copper thick PCB to enhance conductivity and heat dissipation capabilities. The use of mount heat sinks can effectively reduce the temperature of PCBs. The connection between PCB and wires uses patch nuts, and wires can also be directly soldered for convenience and speed. Working voltage range: DC 9-72V (not suitable for direct rectification of 220V mains power!)! )Communication: 7-48VAC Input frequency range: DC --60Hz (default); Output current range: 0-10A continuous current 25 ℃; 10-20A (requires enhanced heat dissipation) Color: As Shown Material: PCB Package Contents: 1 x Ideal Diode Rectifier Bridge Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
